You Know She Knows It

Don't declare that it's magnificent.  She knows it is, in part because she is.  You know it is - in part because you are - but that's not enough.  You need to recognize that you know it and she knows it too, but most importantly of all that you know she knows it, and therefore don't have to declare it.  The thrill isn't in what's explicit, it's in what's implicit.
